CAR-STARE.

To all whom it may concern:

Be it known that I, JOHN W. SILFBERG, a citizen of the United States, residing at Tacoma, in the county of Iierce and State of Washington, have invented a new and useful Improvement in Car-Stakes, of which the following is a specification.

This invention relates to car stakes, and especially to stakes for logging cars, and has for its objects to provide a stake which will not extend beyond the side of the car; which, when withdrawn, is not in the way of any structure on which the logs are to be rolled; and which is cheap to make and easy to operate. I attain these and other objects by the devices, mechanisms and arrangements illustrated in the accompanying` drawings in which- Figure 1 is a plan of a portion of a car equipped with my improved stake, showing a portion of the car deck broken away to reveal the stake-operating mechanism; Fig. 2 is a cross-section of such a car showing the stakes in operative position; Fig. 3 is an elevation of the stake operating lever and its latch; and Fig. 4 is an enlarged vertical cross-section of a portion of one side of the car and of the stake, showing also in broken lines the position of the parts of the mechanism when the stake is in withdrawn position.

Similar numerals of reference refer to similar parts throughout the several views.

The car frame is constructed with side sills 1 and intermediate sills 2 running longitudinally, and needle beams 3 ruiming transversely, said frame being covered by suitable decking 4. Holes 5 are cut through the decking, adjacent the inner side of the side sills 1, at such places as it is desired to have the car stakes, and a plate G is passed through each such hole and secured against the side sill 1 and bent over the edge of the hole on top of the deck 4. A U-shaped plate 7 is secured to the plate G under the hole 5 in the deck 4, and forms with the plate 6 a stake pocket. Under each side of the car is supported an operating shaft 8, said shafts being suitably supported in bearings and positioned above the needle beams 3 and between the side sills 1 and the adjacent intermediate sills 2. rI`hese operating shafts S carry, in line with the stake pockets, the stake arms 9, said arms being securely fastened to the shafts by any suitable means and extending therefrom in the Specification of Letters Patent.

direction of the above-described stake pockets. The stakes 10 consist of channelshaped metal pieces having their flanges facing inward and having the upper portions of said flanges cut on an incline, substantially as shown, and are pivotally secured" to the ends of their respective stake arms 9 by means of pins or bolts 11. The stakes assume an outwardly inclined position when in operative position so that their upper ends substantially reach the sides of the car. It is evident that the stakes 10 are supported and controlled by the arms 9 and that the position of the stakes on one side of the car is controlled by the shaft 8 on that side. The shaft 8 is controlled from the oppositie side of the car, by means of the operating lever 12, a rod 13 secured thereto and connecting it to the end of the arm 1K1 secured to the shaft 8. The lever 12 is pivoted at one end to one of the needle beams 3 and supported at its other end between two guide bars 15 and 16 secured to the side sill 1 and the next intermediate sill 2. This operating lever 12 is adapted to slide transversely of the car between the bars l5 and 1G and thus to turn the shaft S and operate the stakes 10 on the other .side of the car. A latch 17 is pivoted near the inner end of the guide bars in such a way as to normally have its upper end extending across the space between the bars 15 and 1G and so that the lever 12 can be pushed inward therepast but is locked against outward motion by the end of the latch 17 until the latch is turned downward by hand, thus allowing the lever to be drawn outward to lower the stakes on the other side of the car.

Having described my invention what I claim is:

1. In a car stake, the combination with a car frame; a shaft supported longitudinally thereon; stake arms secured to the shaftand extending sidewise therefrom stakes mounted on said arms and extending upward therefrom; means for operating said shaft; and means for holding said shaft from rotation.

2. In a car stake, the combination with a car frame; a shaft supported longitudinally thereon below the deck thereof; stake arms secured to the shaft and extending sidewise therefrom; stakes mounted on said arms and extending upward therefrom through the deck; an operating lever pivoted to the frame on the other side of the car from the shaft and having horizontal transverse motion at one end; an arm secured to the shaft; a rod secured to the operating lever and to said arm whereby said arm and shaft are operated; and means for holding said operating lever from motion.

3. In a ear stake, the combination with a ear frame; a shaft supported longitudinally thereon below the deok thereof; stake arms secured to the shaft and extending sidewise therefrom; stakes mounted 0n said arms and extending upward therefrom through the deck; horizontal transverse guides se- Cured to the frame atthe other side of the ear; an operating lever' pivoted to the frame and having horizontal transverse motion at one end between said guides; an arm secured to the shaft; a rod secured to the operating lever and to said arm whereby Said arm and shaft are operated; and a latch pivoted to said guides and adapted to allow said. lever to move inward therepast but to prevent the outward movement thereof.
